Deinococcus prospects

Deinococcus wulumuqiensis sp. nov., and Deinococcus xibeiensis sp. nov., isolated from radiation-polluted soil.

The taxonomic positions of two gamma- and UV-ray-resistant strains isolated from radiation-polluted soil in north-west China were determined in a polyphasic study. The organisms, designated R12(T) and R13(T), were Gram-stain-positive, non-spore-forming cocci, which contained MK-8 as the major respiratory quinone and C(16 : 1)omega7c and C(16 : 0) as major fatty acids. The cell walls of strains ...

Predicted Cold Shock Proteins from the Extremophilic Bacterium Deinococcus maricopensis and Related Deinococcus Species

While many studies have examined the mechanisms by which extremophilic Deinococci survive exposure to ionizing radiation, very few publications have characterized the cold shock adaptations of this group, despite many species being found in persistent cold environments and environments prone to significant daily temperature fluctuations. Bacterial cold shock proteins (Csps) are a family of cons...

Reclassification of Deinococcus xibeiensis as a Heterotypic Synonym of Deinococcus wulumuqiensis | Charles River

Identification and properties of the Deinococcus grandis and Deinococcus proteolyticus single-stranded DNA binding proteins (SSB).

To study the biochemical properties of SSB's from Deinococcus grandis (DgrSSB) and Deinococcus proteolyticus (DprSSB), we have cloned the ssb genes obtained by PCR and have developed Escherichia coli overexpression systems. The genes consist of an open reading frame of 891 (DgrSSB) and 876 (DprSSB) nucleotides encoding proteins of 296 and 291 amino acids with a calculated molecular mass of 32.2...

Firm but slippery attachment of Deinococcus geothermalis.

Bacterial biofilms impair the operation of many industrial processes. Deinococcus geothermalis is efficient primary biofilm former in paper machine water, functioning as an adhesion platform for secondary biofilm bacteria. It produces thick biofilms on various abiotic surfaces, but the mechanism of attachment is not known. High-resolution field-emission scanning electron microscopy and atomic f...
